Hormone may help fight obesity and reduce cholesterol

A variant of FGF21, LY2405319, has been shown to improve metabolism in obese humans with type 2 diabetes by reducing LDL cholesterol and triglycerides while increasing HDL cholesterol levels. The hormone also reduced body weight and fasting insulin, and increased adiponectin.

The true raw material footprint of nations

A new Australian study uses a novel modelling tool to calculate the 'material footprint' of 186 countries over two decades, revealing that pressures on raw materials do not decline with economic growth. The results confirm that decoupling of natural resources from economic growth has been exaggerated.

A fly's hearing

Researchers at the University of Iowa used fruit flies to study hearing loss caused by loud noise. The study found that the molecular underpinnings of hearing loss in fruit flies are similar to those in humans.

Treatment with the anti-diabetic drug alogliptin does not increase CV risk in patients with ACS

Patients with type 2 diabetes and high cardiovascular risk have similar rates of cardiovascular events when treated with alogliptin compared to placebo, according to the Examination of Cardiovascular Outcomes with Alogliptin versus Standard of Care trial. The findings provide reassurance for clinicians treating patients with type 2 dia...

Prehistoric climate change due to cosmic crash in Canada

A Dartmouth-led team reveals that an asteroid impact in Quebec led to a global climate shift 12,900 years ago, causing the extinction of large mammals and prompting humans to adopt a hunter-gatherer diet. The study provides conclusive evidence linking extraterrestrial activity to environmental transformation.

Exploitation of Indian workers on 457 visas

A recent study published in The Economic and Labour Relations Review reveals the exploitation of Indian immigrant workers in Australia on 457 visas. The researchers found that workers are often forced to work long hours for low pay under substandard conditions, with little choice but to sign revised contracts or face deportation.

Soot suspect in mid-1800s Alps glacier retreat

Scientists have uncovered strong evidence that soot from industrial Europe caused the abrupt retreat of mountain glaciers in the European Alps. The research, published in Proceedings of the National Academy of Sciences, resolves a longstanding debate about why the Alps glaciers retreated beginning in the 1860s.

Breakthrough in sensing at the nanoscale

The discovery enables rapid localization and measurement of cells within living environments at the nanoscale, such as changes to a single cell in response to chemical signals. The ultra-sensitive nanoparticles, or SuperDots, can detect individual particles with thousand times more sensitivity than existing materials.
